Numerical Simulation in Combustion Space of an Oxy-fuel Glass Furnace with Different Jet Angles of Auxiliary Oxygen

摘要：

Numerical simulation in the combustion space of an oxy-fuel glass furnace was carried out. In order to obtain better combustion efficiency, the cases by adding auxiliary oxygen inlet with different jet angles of auxiliary oxygen from 0 degrees to 90 degrees were compared. The gas phase is expressed with two-equation model, while the combustion with non-premixed model and the radiation with DO radiation model. According to the simulation results, the way adding auxiliary oxygen inlet contributes to improve combustion efficiency and achieve appropriate temperature distribution. The flame shape keeps relative rational in small angles (from 0 degrees to 50 degrees) but becomes irregular after 50 degrees. Especially in 30 degrees, not only the heat transfer rate to the bottom surface reaches a maximum value, but also the average temperature of the cross middle slice of burners height is high.
